“Zero Leakage” inlet guide Vanes• Adjustable inlet guide vanes provide optimum flow patterns as

well as precise and continuous control across the machine’s full operational spectrum

• Self-energizing back plate maintains zero sidewall clearance for maximum expander efficiency

• Zero backlash variable guide vane configuration provides smooth turn-up capability to 125% of design flow

Rugged Rotor Design• Stiff rotor shaft and high capacity tilt pad bearings assure maximum

stability at all operating loads and speeds• High capacity tilt pad thrust bearings provide the extra margin

necessary to handle transients• Numerous bearing designs available to accommodate specific

process applications, including hydrodynamic (journal and tilt pad) bearings, ball bearings, ceramic bearings, and air/foil bearings

• Sealing design offers robust construction and reliable performance

Dual independent Labyrinth shaft seal• Reliable teeth-on-shaft design is precision machined to ultra

close clearances, minimizing seal gas consumption• Dual port, atmospheric center vent prevents process stream

contamination

self-Aligning Wheel Attachment• Tapered bore and stretch rod design automatically compensates

for thermal and mechanical changes to maintain alignment under all operating conditions

• Precision machined tapered bore/shaft attachment allows independent balancing of turbine wheel and shaft to facilitate field repair
